Damage to the car air conditioning compressor can lead to the following issues: 1. The air conditioning fails to cool, which is the most obvious sign of compressor failure; 2. Cracks appear in the compressor drive belt; 3. When the compressor is operating, the cooling system activates, resulting in abnormal fan noise or the fan not rotating; 4. Abnormal intermittent engagement of the clutch; 5. Abnormal noise from the compressor clutch bearing. The main causes that can easily lead to air conditioning compressor damage include: 1. The air conditioning system is unclean, with particulate impurities being sucked into the compressor; 2. Excessive refrigerant or lubricating oil in the system, causing "liquid slugging" and damaging the compressor; 3. The compressor operates for a long time under high temperature and high pressure conditions; 4. Severe oil shortage in the compressor, leading to significant wear; 5. The electromagnetic clutch of the compressor slips, causing excessive friction temperature; 6. The compressor's power configuration is too small; 7. There are defects in the manufacturing quality of the compressor.

Multimeters have settings for measuring voltage, resistance, and current. To measure car current leakage, rotate the knob to the current measurement setting. 2. Select the measurement range. For most vehicles, the 20A range is appropriate. Then insert the red probe into the socket marked 20A. 3. After adjusting the multimeter, turn off the vehicle's engine, shut down all electrical devices, and lock the doors. 4.

How to Maintain Car Tires in Summer?

Methods for maintaining car tires in summer: 1. Park reasonably. During summer, park the car in a place without prolonged exposure to sunlight, as long-term exposure to UV rays can cause the rubber surface to age, increasing the risk of tire blowouts. 2. Inflate with nitrogen to prevent blowouts: Filling tires with nitrogen can reduce the likelihood of blowouts and prevent spontaneous combustion. 3. Do not splash water on tires to cool them down: After driving on the highway for two hours, park the car in a shaded area to let the tires rest and cool down naturally. Avoid splashing water on the tires to prevent deformation. When cooling and reducing tire pressure, allow them to cool naturally. Methods like splashing cold water on the tires can easily cause cracks and shorten the tire's lifespan.

Can You Park on a Slope?

Cars can be parked on a slope, but safety precautions must be taken. Here are some tips for parking on a slope: Parking on an uphill roadside: After parking, shift the gear lever to first gear. If there is a curb, turn the front wheels to the left at a certain angle so that the rear of the right front wheel is close to or against the curb to prevent the car from rolling backward. If there is no curb, turn the front wheels to the right at a larger angle to avoid the car rolling backward into the center of the road. Parking in an uphill area of a parking lot: After parking, shift the gear lever to first gear and turn the front wheels to the left or right at a certain angle. This prevents the car from rolling backward continuously. If the slope is steep, additional measures should be taken, such as placing stones behind the rear wheels.
